Typedef Documentation

ru_Int64

typedef void* ru_Int64

A pointer to an allocated 64 bit int. Free with ruFree.

Function Documentation

ruInt64()

RUAPI ru_Int64 ruInt64

(

ptr

val

)

Allocates given 64 bit integer on the heap and returns the pointer.

Parameters

val	address where int to allocate is stored

Returns

Pointer to allocated integer. Caller must free with ruFree

ruInt64Comp()

RUAPI int32_t ruInt64Comp	(	trans_ptr	testVal,
		trans_ptr	existingVal
	)

64 bit integer comparator function for the ruType system

Parameters

testVal	Value to compare against existing value.
existingVal	The existing value to compare testVal to.

Returns

-1 if testVal is less existingVal, 1 if testVal is greater existingVal or 0 in case both of them are equal.

ruInt64Hash()

RUAPI ru_uint ruInt64Hash

(

trans_ptr

key

)

Returns a hash for given 64 bit integer number.

Parameters

key	Number to hash

Returns

The hash of the given number.

ruInt64Match()

RUAPI bool ruInt64Match	(	trans_ptr	s1,
		trans_ptr	s2
	)

Convenience 64 bit integer match function for Maps.

Parameters

s1	First comparison int.
s2	Second comparison int.

Returns

true if they are equal

ruRefPtrInt64()

RUAPI int32_t ruRefPtrInt64	(	ptr	src,
		ptr *	dst
	)

Copies the 64 bit integer stored in src to dst.

Parameters

src	Where the 64 bit integer is stored, usually in the collection.
dst	Where the value will be copied to properly type casted.

Returns

RUE_OK unless dst is not set.

ruTypeInt64()

RUAPI ruType ruTypeInt64

(

void

)

Returns an ruType used for 64 bit integers.

Example:

// error checking left out for brevity
int64_t k1 = 23, v1 = 42, r = 0;
ruMap rm = ruMapNew(ruTypeInt64(), ruTypeInt64());
ruMapPut(rm, &k1, &v1);
 
ruMapGet(rm, &k1, &r);
printf("k: %ld v: %ld\n", k1, r);
ruMapFree(rm);

Returns

64 bit integer type specification. Caller need not free.
